RELATED APPLICATION

The present application claims the benefit of U.S. Provisional Application No. 60/778,198 filed Mar. 2, 2006, which is incorporated herein in its entirety by reference.

BACKGROUND OF THE INVENTION

This invention relates to lecterns. More particularly, this invention is a multi-piece lectern with loop-frame construction adapted to receive a removable front panel.

Lecterns are used in a variety of applications. Primarily, lecterns are used by individuals who are delivering a speech, lecture, or other oral or visual presentation to an audience. Also commonly called podiums, lecterns can enhance the ability of a speaker to deliver an effective presentation.

The disclosures of the aforementioned patents are hereby incorporated by reference.

A lectern provides an accessible elevated surface on which a speaker may place items for use during a presentation. The elevated surface may, for example, support notes, documents, papers, a computer, or other materials a speaker wishes to reference. The elevated surface may also support objects a speaker shows or distributes to members of an audience. Additional surfaces can increase the number of materials at the disposal of a speaker, while the location of such surfaces on the lectern can influence the type of materials placed on the surfaces.

In addition to providing an elevated surface, a lectern can enhance a speaker's comfort. For example, a speaker who likes to keep his or her hands occupied can grasp the lectern while speaking. In addition, the speaker can rest on the lectern to alleviate some of the physical stress of standing for a prolonged period. A lectern also provides a physical barrier between the speaker and the audience which can create a sense of security for the speaker and help the speaker gain self-confidence. The presence of a lectern also provides the speaker with an available prop. Therefore, there is a need for a structurally sound lectern that can support significant weight and is durable.

A lectern is often situated as a visual and audio focal point. Therefore, lecterns can significantly affect how a speaker is perceived by an audience. The height of the lectern with respect to the speaker, for example, may influence impressions relating to the speaker's physical stature. In other instances, the lectern itself can create an orderly appearance by hiding materials the speaker may have brought to the lectern. The shape and overall design of the lectern, including the presence of printed matter and images, may further influence how an audience perceives the speaker.

Since a lectern may be a visual or audio focal point, it may be desirable for the lectern itself to continuously convey a visual message to an audience. For example, a speaker may wish to show a symbol or phrase that helps the audience identify who the speaker is or associate the speaker with a particular organization. Alternatively, a company may wish to use the presence of a well-known speaker to advertise a particular product to the audience. Alternatively, a proprietor of the location where the speaker is presenting may wish to remind the audience of the location.

Since most lecterns are situated in front of an audience, the messages are ideally displayed on interchangeable panels visible from the front. The panels should not unduly obstruct the speaker or interfere with lectern surfaces that the speaker may wish to use. When disposed to the lectern, the panels should be made so as not to appear homemade or make-shift. Panels should be readily producible on an individual basis while easily employing the attachment mechanisms of the lectern as originally manufactured. Production defects or desired or accidental dimensional variations that occur when personalized panels are made should not cause the panels to be awkwardly disposed to the lectern. The lectern should not require disassembly or significant reconfiguration in order for the panels to be attached or removed.

Therefore, there is a need for a lectern that reduces cost, can be stored easily, is reuseable, transportable and is adapted to receive a removable front panel, and is structurely sound.

SUMMARY OF THE INVENTION

To address the aforementioned needs, this invention provides a lectern constructed from top and bottom members disposed between two side panels. These components are assembled to form a lectern of loop-frame construction. Additional members traversing the loop frame are structurally unnecessary. In preferred embodiments, however, a front panel made from flexible material can be disposed within the loop-frame construction. The front panel can be inserted or removed without disassembling or reassembling the lectern.

The loop-frame construction of this invention offers several benefits over the existing art. Loop-frame construction gives a speaker the option of attaching a front panel to the frame or enhancing speaker visibility by not attaching the front panel. Loop-frame construction also minimizes the amount of material used in manufacturing the lectern, which reduces costs and makes transporting and moving the lectern easier by reducing the overall weight of the lectern. Since unassembled components can be arranged so as to reduce bulk, loop-frame construction permits lecterns to be shipped more efficiently than lecterns made from a unitary piece of material. Loop-frame construction also permits the lectern to be assembled from more than one type of material and from materials, such as metal, that would be costly and difficult to use in molded construction.

Structurally, the loop-frame construction of this lectern comprises four primary components. In preferred embodiments, support (top) and base (bottom) members are disposed between two side panels. The two side panels provide the vertical structure and account for the height of the lectern. The support and base members provide the horizontal structure and primarily account for the width of the lectern. The depth of the lectern can vary depending upon the shapes of the side panels, but generally approximates the depth of the support and base members.

In addition to providing structural support, the support and base members can also assist a speaker in delivering an effective presentation. The top surface of the support member supports objects and materials a speaker may use during a presentation. The top surface of the base member provides a surface on which the speaker can rest one of his or her feet while standing. The side panels provide a surface that the speaker can hold, while the shape of the side panels gives a streamlined appearance to the lectern and can reduce the force of impact in the event the lectern tips over. The removable front panel provides a medium for visually conveying a written message, image, or other depiction to an audience and adds to the barrier between the speaker and the audience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention is directed to a lectern, as illustrated at 10 in FIG. 1. As shown in FIGS. 2-5, lectern 10 generally includes side panels 20, 22, hollow support member 24, and hollow base member 26 assembled in a loop-frame construction. Front panel 28 can be disposed to lectern 10 so as to be removably extended between hollow support member 24 and hollow base member 26.

Side panels 20, 22 support hollow support member 24 and hollow base member 26 at selected distances above a floor (not shown). Side panels 20, 22 and hollow support member 24 provide support for objects and materials a speaker may use during a presentation and structurally support lectern 10. Side panels 20, 22 and hollow base support member 26 provide support for a speaker to comfortably rest one of his or her feet during a presentation and structurally support lectern 10.

Hollow support member 24 and hollow base member 26 are disposed between side panels 20, 22 in a manner that reduces the inherent susceptibility of loop-frame construction to shear stresses. Shear stresses in lectern 10 occur when an applied lateral force is opposed by friction, or other opposing force, between lectern 10 and the floor. Without suitable disposition between side panels 20, 22 and support and base members 24, 26, the components and joints of lectern 10 can fatigue, crack, rupture, or otherwise become damaged due to shear stresses. This dilemma can be exacerbated through the manufacture of side panels 20, 22 from various materials that provide relatively poor anchors for fastening members 31. The shear stress on lectern 10 caused by a speaker leaning on one of side panels 20, 22, for example, may cause fastening members 31 to disengage from side panels 20, 22, such as when a screw is stripped out of plywood. This invention reduces damage to lectern 10 due to shear stresses by maximizing the surface contact where side panels 20, 22 and support and base members 24, 26 are adjoined and by providing an improved anchor for fastening members 31.

Hollow support member 24 may generally include main support body 40 and first and second side support plates 42, 44, as most clearly illustrated in FIGS. 3-5 and 7. Main support body 40 may generally include top support wall 41, anterior wall 43, and bottom support wall 45. In preferred embodiments, main support body 40 has top support wall 41 that is oriented at an angle to enhance the ability of the speaker to view items placed on lectern 10. The angle of elevation of top support wall 41 with respect to a level surface, such as a floor, may be in the range of about zero degrees to about sixty degrees. In preferred embodiments, the angle of elevation is about seventeen degrees.

Main support body 40 and side support plates 42, 44 may be formed from a variety of materials depending upon the intended use of lectern 10. In preferred embodiments, main support body 40 and side support plates 42, 44 are made from powder coated metal. In other embodiments, main support body 40 and side support plates 42, 44 are painted. The thickness of main support body 40 and side support plates 42, 44 may be in the range of about four gauges to about thirty gauges. In preferred embodiments, the thickness of main support body 40 and side support plates 42, 44 is about twelve gauges.

As illustrated in FIG. 5, hollow support member 24 may include shaft 54 mounted to top support wall 41 proximate a posterior edge of top support wall 41. In preferred embodiments, shaft 54 is positioned near the posterior end of top support wall 41 so as to enable certain papers, notes, or other materials to remain on hollow support member 24 without falling off. In other embodiments, shaft 54 may be positioned proximate as anterior end of top support wall 41 so as to enable objects, such as, for example, a clip-on light, to be secured to hollow support member 24. Shaft 54 generally includes an elongated bar, but may be any suitable geometry. As shown in FIG. 8, shaft 54 may be hollow. Shaft 54 may have end caps 56 attached at each end, as shown in FIGS. 5 and 9. In an embodiment, inner portion 58 of end cap 56 coextensively mates with elongated bar 54 so that outer portion 57 of end cap 56 extends over a portion of top support wall 41. As shown in FIG. 9, end caps 56 have a rounded-end configuration. End caps 56 may be fabricated from a variety of materials, such as, for example, injection-molded acrylonitrile butadiene styrene (ABS).

In preferred embodiments, shaft 54 is fabricated from substantially square aluminum tubing. In other embodiments, shaft 54 is substantially cylindrical. The thickness of material from which shaft 54 is made may be in the range of about one-fourth of one millimeter to about ten millimeters. In preferred embodiments, the thickness of shaft 54 is about one millimeter. Embodiments in which shaft 54 is substantially quadrilateral, as illustrated in FIG. 8, may have a z-axial height in the range of about one-fourth of one inch to about six inches, a y-axial depth in the range of about one-fourth of one inch to about six inches, and an x-axial width in the range of about one inch to about forty-eight inches. In preferred embodiments, shaft 54 has a z-axial height of about three-fourths of one inch, a y-axial width of about three-fourths of one inch, and an x-axial length of about sixteen inches. Embodiments in which shaft 54 is substantially cylindrical may have a diameter in the range of about one-fourth of one inch to about six inches and a width in the range of about one inch to about forty-eight inches. In other embodiments, shaft 54 may be cylindrical with a diameter of about three-fourths of one inch and a length of about 16 inches. Shaft 54 may be made from a variety of materials, such as, for example, metal, wood, or plastic, into a variety of shapes. In preferred embodiments, shaft 54 is made from metal.

Hollow base member 26 may generally include main base body 70 and first and second side base plates 72, 74, as most clearly illustrated in FIGS. 3-5 and 12. Main base body 70 may generally include top base wall 71, posterior wall 73, and bottom base wall 75. In preferred embodiments, main base body 70 has top base wall 71 that is oriented at an angle to allow a speaker to comfortably place one of his or her feet on lectern 10. The angle of declination of top base wall 71 with respect to a level surface, such as a floor, may be in the range of about zero degrees to about sixty degrees. In preferred embodiments, the angle of declination is about seventeen degrees.

Main base body 70 and side base plates 72, 74 may be formed from a variety of materials depending on the intended use of lectern 10. In preferred embodiments, main base body 70 and side base plates 72, 74 are made from powder coated metal. In other embodiments, main base body 70 and side base plates 72, 74 are painted. The thicknesses of main base body 70 and side base plates 72, 74 may be in the range of about four gauges to about thirty gauges. In preferred embodiments, the thicknesses of main base body 70 and side base plates 72, 74 are about twelve gauges.

Proximate a front edge of main base body 70, main base body 70 may have apertures 80. Apertures 80 are designed to at least partially receive wheels 82 to facilitate moving lectern 10 to a desired location. In preferred embodiments, wheels 82 are attached to main base body 70 with axle 84. In other embodiments, wheels 82 are attached directly to main base body 70. In preferred embodiments, wheels 82 do not make contact with the floor when lectern 10 is in an upright position.

Side panels 20, 22 may have a variety of shapes. Side panels 20, 22 may be shaped substantially similar to each other. In preferred embodiments, left side panel 20 is substantially a mirror image of right side panel 22, as shown in FIGS. 1-5. Upper edges 30 of side panels 20, 22 may be oriented at an angle with respect to lower edges 32 of side panels 20, 22, as illustrated in FIGS. 3-5. Front edges 34 of side panels 20, 22 may have a convex shape and back edges 36 of side panels 20, 22 may have a concave shape. By shaping front edges 34 to have a convex geometry, lectern 10 will roll along front edges 34, similar to a rocking chair, if lectern 10 is tipped onto front edges 34. This may reduce the force of impact of lectern 10 on the floor, thereby minimizing damage to lectern 10 and to the floor in the event lectern 10 is tipped over. Panels having convex front edges 34 and concave back edges 36 also enhance the overall appearance of lectern 10.

Side panels 20, 22 may be fabricated from a variety of materials. To enhance the durability of lectern 10, the material from which side panels 20, 22 are made should be strong enough to support support member 24, base member 26, and a typical weight range of an adult person. The material should also be able to withstand substantial shear stress along the support member 24 and base member 26. Depending upon the intended use of lectern 10, side panels 20, 22 may be made from, for example, medium density fiber core (MDF) plywood or other wood product, metal, acrylic or other polymeric material, or other substantially sturdy material or combination of materials. Similarly, side panels 20, 22 may be painted or covered with a laminate. For disposable use, side panels could be made of a lightweight material such as, for example, cardboard. In preferred embodiments, lectern 10 is made from MDF plywood.

Referring to FIG. 6, front edges 34 of side panels 20, 22 may have a height H₃₄-H₃₄ in the range of about twelve inches to about ninety-six inches. In preferred embodiments, front edges 34 of side panels 20, 22 have a height H₃₄-H₃₄ of about fifty-four inches.

In preferred embodiments, back edges 36 of side panels 20, 22 have a height H₃₆-H₃₆ of about forty-four inches. Side panels 20, 22 may have a width W-W in the range of about twelve inches to about forty-eight inches. In preferred embodiments, side panels have a width W-W of about twenty-two inches. Side panels 20, 22 may have a thickness in a range of about one-sixteenth of one inch to about four inches. In preferred embodiments, side panels 20, 22 have a thickness of about three-fourths of one inch.

As shown in FIGS. 4 and 5, side support plates 42, 44 are attached to main support body 40 proximate opposite ends of main support body 40. Side support plates 42, 44 have apertures 48 to facilitate attaching hollow support member 24 to side panels 20, 22. Hollow support member 24 may be attached to each of side panels 20, 22 by inserting fastening members 31 through apertures 48 in side support plates 42, 44 and through apertures 49 in side panels 20, 22. In preferred embodiments, hollow support member 24 is attached to side panels 20, 22 by anchoring fastening members 31 in first and second upper cover plates 60, 62. In other embodiments, fastening members 31 are anchored in side panels 20, 22. To facilitate the attachment of hollow support member 24 and to help reduce shear stress on lectern 10, fastening members 31 are anchored in hollow extensions 64 of first and second upper cover plates 60, 62. Hollow extensions 64 of first and second upper cover plates 60, 62 extend through apertures in side panels 20, 22. In preferred embodiments, hollow extensions 64 are spaced apart so as to reduce shear stress on lectern 10. Hollow extensions 64 also facilitate alignment of screws with apertures 48 in side support plates 42, 44.

First and second upper cover plates 60, 62 may each have a shape that substantially conforms to a side profile of main support body 40. In preferred embodiments, first and second upper cover plates 60, 62 are substantially mirror images. First and second upper cover plates 60, 62 may be fabricated from a variety of materials depending upon the intended use of lectern 10. In preferred embodiments, first and second upper cover plates 60, 62 are fabricated from powder coated metal similar to the material of main support body 40.

As shown in FIGS. 4 and 5, side base plates 72, 74 are attached to main base body 70 proximate opposite ends of main base body 70. Side base plates 72, 74 have apertures 78 to facilitate attaching hollow base member 26 to side panels 20, 22.

In preferred embodiments, first and second lower cover plates 90, 92 are fabricated from powder coated metal similar to the material of main base body 70.

Loop-frame construction of lectern 10 is generally adapted to receive front panel 28. As shown in FIG. 15, removable front panel 28 generally has main section 100, top end 101, and bottom end 103. In preferred embodiments, front panel 28 may be removably extended between hollow support member 24 and hollow base member 26. Front panel 28 may be readily attached to or detached from hollow support member 24, hollow base member 26, or both such that lectern 10 need not be disassembled or reassembled. In other embodiments, front panel 28 is removably extended between side panels 20, 22. Front panel 28 may be fabricated with a color, design, name, or message as desired. Front panel 28 may be fabricated from a variety of materials, such as, for example, fabric or metal, depending on the intended use of the lectern 10. In preferred embodiments, front panel 28 is made from a flexible fabric material.

Removable front panel 28 may be extended between hollow support member 24 and hollow base member 26 in any number of ways. In preferred embodiments, hollow support member 24 and hollow base member 26 are adapted to receive front panel 28. As shown in FIGS. 7 and 10, main support body 40 may contain upper slot 52. As shown in FIGS. 12 and 13, main base body 70 may contain lower slot 76. Upper slot 52 has dimensions such that top end 101 of front panel 28 fits through upper slot 52. Lower slot 76 has dimensions such that bottom end 103 of front panel 28 fits through lower slot 76.

Top end 101 and bottom end 103 may be adapted in any number of ways in order to secure front panel 28 to support and base members 24, 26. Bottom end 103 may be constructed so as to receive retaining rod 102, as shown in FIGS. 16, 18, and 19. In preferred embodiments, bottom end 103 is attached to front panel 28 to create receiving loop 107.

Retaining rod 102 can be inserted through and into receiving loop 107. Top end 101 may also be constructed so as to receive retaining rod 102. Retaining rod 102 may be of any suitable shape and made from any substantially rigid material. In preferred embodiments, retaining rod 102 is cylindrical and made of aluminum. Diameter of retaining rod 102 may be in the range of about one-sixteenth of one inch to about three inches. In preferred embodiments, diameter of retaining rod is about one-half of one inch. Retaining rod 102 is shaped so as not to be able to pass through upper slot 52 or lower slot 76. In preferred embodiments, retaining rod 102 is shaped such that retaining rod 102 and receiving loop 107 nest in, but are substantially unable to pass through, upper slot 52 or lower slot 76. Retaining rod 102 is longer than the upper slot 52 or lower slot 76.

Top end 101 may comprise hook-and-loop fastener 105, as shown in FIG. 18, that can attach to hook-and-loop fastener 105 affixed to an inside surface of hollow support member 24. Alternatively, top end 101 may comprise attachment bracket 104, as shown in FIG. 19. Attachment bracket 104 has apertures 106 that are adapted to engage hooks 33 located in or on hollow support member 24. Bottom end 103 may also be secured to hollow base member 26 by attachment bracket 104 or hook-and-loop fastener 105.

In securing front panel 28 to hollow support member 24 or hollow base member 26, top end 101 and bottom end 103 may comprise the same or different attachment mechanisms. In preferred embodiments, bottom end 103 is secured to base member 26 using retaining rod 102 and top end 101 is secured to support member 24 with hook-and-loop fastener 105. In securing bottom end 103 of front panel 28 to an inside surface of hollow base member 26, bottom end 101 is inserted through lower slot 76. As shown in FIG. 16, retaining rod 102 is fed through receiving loop 107 at bottom end 103 of front panel 28. Although not necessary to secure front panel 28 to hollow base member 26, retaining rod 102 protrudes from both ends of receiving loop 107 in preferred embodiments. In securing top end 101 of front panel 28 to an inside surface of hollow support member 24, top end 101 is inserted through upper slot 52. Hook-and-loop fasteners engage top end 101 with an inside surface of support member 24. In preferred embodiments, front panel 28 is made of a flexible fabric material. This enables retaining rod 102 and receiving loop 107 to engage lower slot 76 when an upward force is applied to engage top end 101 to an inside surface of hollow support member 24. This also ensures that front panel 28 fits snugly between hollow support member 24 and hollow base member 26.

Support member aperture 47 in bottom hollow support wall 45 of support member 24 may facilitate the attachment of top end 101 of front panel 28 by providing a user with easy access into the inside cavity of hollow support member 24. Base member aperture 77 in top base wall 75 of base member 26 may facilitate the attachment of bottom end 103 of front panel 28 by providing a user with easy access into the inside cavity of hollow base member 26.

The loop-frame construction of lectern 10 thereby provides an elevated surface for use by a speaker and, optionally, a removably extended front panel 28. Lectern 10 may be distributed in a relatively compact configuration while enabling an end user to readily assemble lectern 10. Alternative views of lectern 10 are also shown in FIGS. 19-25.
